Pulmonology, Respiratory and Sleep Medicine Risk Assessment: Infection, Equipment and Escalation Controls

A worked example of how a respiratory and sleep medicine service finds, scores and controls risks to patients, from infection spread and equipment faults to missed deterioration, consent gaps and privacy breaches.

Updated November 2026 8 hazards assessed Review every 6 months Highest risk: Critical to Medium
See the Pulmonology, Respiratory and Sleep Medicine course

Executive summary

This assessment shows how a respiratory and sleep medicine service can identify, rate and control the risks that matter most to patient safety and care quality. Eight hazards were selected because they are plausible in everyday work on wards, in clinics, in sleep laboratories and in home care. The highest inherent scores sit with missed clinical deterioration and airborne infection, because both can cause serious harm quickly. Each hazard is scored before controls and again after existing and additional controls. Most risks fall to Low or Medium once the proposed actions are in place, though deterioration and infection stay at Medium because their impact remains serious. The first actions are a structured handover and escalation tool, fit testing and isolation checks, a ventilator and oxygen alarm review and a consent audit. This is an educational example, not clinical guidance. Any real service needs a formal, site-specific assessment led by qualified clinicians and governance staff.

Focus area
Pulmonology, respiratory and sleep medicine
Setting
Respiratory and sleep service within a general hospital, with outpatient clinics, inpatient beds, a sleep laboratory and home therapy support
Method
Five by five likelihood and impact risk register

Scope

This assessment covers a respiratory and sleep medicine service, including outpatient clinics, inpatient respiratory beds, a sleep laboratory and home therapy support. It looks at risks to patient safety, privacy, consent, equipment and continuity of care. It does not give clinical instruction or replace a site-specific assessment. Jurisdiction, staffing levels, equipment suppliers and record systems are assumptions made for teaching.

Context

The service has consultant pulmonologists, respiratory nurses, physiologists, sleep technologists, a ward team and administrative staff. Patients attend clinics, stay on respiratory wards, undergo bronchoscopy and sleep studies, and go home on oxygen or positive airway pressure therapy. Records sit in an electronic patient record, with monitoring equipment and ventilators feeding alarms to the ward. Each risk is scored before controls to show its natural level, then again after existing controls and the additional controls proposed here.

Objectives, assets and stakeholders

The objective is to deliver safe, timely and respectful respiratory and sleep care, prevent harm, protect privacy and keep the trust of patients and referrers. Assets in scope include patients, staff, beds and monitoring equipment, oxygen and ventilation systems, the electronic record and sleep study data. Stakeholders include patients and families, clinicians, nurses, technologists, managers, referring doctors, equipment suppliers, the governance board and regulators. Every risk has one owner role, and the clinical governance lead keeps the register current and reports to the service board each quarter.

H01

Airborne and healthcare associated respiratory infection spread

Safety Before 16 After 6

Respiratory infections spread between patients, visitors and staff through coughing, aerosol generating procedures and shared equipment, especially where isolation rooms or fit tested masks are not used consistently.

Who or what is affected: Patients, visitors, nurses and physiologists

Causes

Unrecognized infection on arrival, crowded waiting areas and shared equipment used between patients.

Consequences

Outbreak, transmission to staff, ward closure and serious harm to vulnerable patients.

Existing controls

  • Isolation rooms are used for suspected infections.
  • Staff wear masks during aerosol generating procedures.

Control gaps

Fit test records are not checked against the current rota, so untested staff may still work with suspected cases.

Additional controls

  • Prevent: Fit test staff and check isolation room pressure before admitting suspected cases.
  • Detect: Audit mask use and hand hygiene each month and record the results.
Likelihood 4 x impact 4 before; 2 x 3 after Owner: Infection prevention lead Target: Within 30 days Early warning: Two or more linked infections identified on the same ward within a week.
H02

Ventilator and oxygen equipment failure or misuse

Operational Before 15 After 6

Ventilators, oxygen concentrators or cylinders are set up wrongly, not checked before use, or fail during therapy, so a patient receives too little or too much support.

Who or what is affected: Inpatients, home therapy patients and ward staff

Causes

Misconfigured settings, untrained users, ageing devices and alarms that are silenced.

Consequences

Hypoxia, hypercapnia, device related harm and emergency transfer.

Existing controls

  • Equipment is serviced on a planned schedule.
  • Alarms sound at the nurse station when settings change.

Control gaps

Alarm limits are set by default and are not reviewed for each patient.

Additional controls

  • Prevent: Use a daily pre-use checklist with a second person sign off for each ventilator.
  • Respond: Keep a tested backup device and a written swap procedure on every ward.
Likelihood 3 x impact 5 before; 2 x 3 after Owner: Biomedical engineering lead Target: Within 45 days Early warning: Alarms overridden or silenced without a documented reason.
H03

Medication and sedation errors during procedures and sleep studies

Safety Before 15 After 8

Inhaled, nebulized or sedative medicines are given at the wrong dose, to the wrong patient or without monitoring during bronchoscopy, sleep studies or ward therapy.

Who or what is affected: Patients receiving sedation, nurses, doctors and technologists

Causes

Look alike drug names, rushed medication rounds and errors in weight or age used for dosing.

Consequences

Respiratory depression, aspiration, allergic reaction and avoidable admission.

Existing controls

  • Prescriptions are checked by a pharmacist before supply.
  • Sedation is given only by trained staff with monitoring equipment.

Control gaps

Nebulizer doses are rarely double checked on the ward.

Additional controls

  • Prevent: Use a two identifier check and a dose check before every sedative or nebulized dose.
  • Detect: Review sedation records and adverse events weekly and feed findings into training.
Likelihood 3 x impact 5 before; 2 x 4 after Owner: Clinical pharmacist lead Target: Within 30 days Early warning: Two or more near miss reports for sedation or nebulizer doses within a month.
H04

Missed clinical deterioration and delayed escalation

Safety Before 20 After 8

Falling oxygen levels, rising breathlessness or drowsiness are not recognized or escalated in time, especially during handover, night shifts or when patients are on sleep or home monitoring.

Who or what is affected: Inpatients, nurses, junior doctors and outpatients

Causes

High workload, unclear escalation thresholds and handovers that omit key details.

Consequences

Respiratory arrest, unplanned intensive care, avoidable death and serious harm.

Existing controls

  • Observations are recorded on a set schedule.
  • An early warning score prompts a review when raised.

Control gaps

Escalation criteria differ between wards and are not practiced in drills.

Additional controls

  • Prevent: Introduce a structured handover tool that names each patient's respiratory risks and escalation plan.
  • Respond: Set a rapid review route that any staff member can call without seeking permission.
Likelihood 4 x impact 5 before; 2 x 4 after Owner: Clinical lead for respiratory care Target: Within 30 days Early warning: Patients on respiratory wards with a raised score and no documented review within the set time.
H05

Privacy breach of respiratory and sleep records

Technology and data Before 12 After 6

Clinic letters, sleep study recordings or results are viewed, sent or shared by people who have no care reason, or are lost on paper or on unsecured devices.

Who or what is affected: Patients, families and the service

Causes

Shared logins, misdirected post and curiosity about known patients.

Consequences

Distress to patients, loss of trust, regulator complaint and disciplinary action.

Existing controls

  • Records are accessed with individual logins.
  • Staff complete information governance training on joining.

Control gaps

Access logs are not reviewed, and clinic letters are printed and posted without checks.

Additional controls

  • Prevent: Restrict sleep study files to named staff and encrypt any portable storage used.
  • Detect: Review access logs for records viewed outside a care team each month.
Likelihood 3 x impact 4 before; 2 x 3 after Owner: Information governance lead Target: Within 60 days Early warning: Record access by staff outside the care team or sleep service.
H06

Consent and documentation gaps for invasive procedures and home therapy

Legal and compliance Before 12 After 6

Bronchoscopy, pleural procedures, tracheostomy care or home ventilation are started without a signed consent form, a documented decision or a clear record of what was explained to the patient.

Who or what is affected: Patients, families and clinicians

Causes

Time pressure, unclear responsibility for consent and templates that are incomplete.

Consequences

Legal challenge, complaint, withdrawn consent and loss of trust.

Existing controls

  • Consent forms are kept in the clinical notes.
  • Procedures are listed on a daily theatre or clinic list.

Control gaps

Audits cover completed forms only, not whether the discussion took place.

Additional controls

  • Prevent: Check the signed consent form and documented discussion before each procedure starts.
  • Detect: Audit a sample of procedure notes each quarter against the local consent policy.
Likelihood 3 x impact 4 before; 2 x 3 after Owner: Clinical governance lead Target: Within 60 days Early warning: Procedure recorded without a signed consent form or documented decision on the day.
H07

Staffing, competence and handover shortfalls

People Before 9 After 4

Specialist procedures, sleep technology and ward care are delivered by staff who are not signed off for the task, or who cover unfamiliar work when rotas are short.

Who or what is affected: Patients, staff and trainees

Causes

Vacancies, sickness, training backlogs and reliance on a few senior staff.

Consequences

Errors, cancelled procedures, staff burnout and reduced patient safety.

Existing controls

  • Competency sign off is recorded for each procedure.
  • Rotas are reviewed weekly by the ward manager.

Control gaps

Competency records are not checked against rota changes made on the day.

Additional controls

  • Prevent: Match each procedure list to named competent staff before the session starts.
  • Respond: Keep a bank of trained cover staff and a documented plan for short notice gaps.
Likelihood 3 x impact 3 before; 2 x 2 after Owner: Service manager Target: Within 90 days Early warning: Procedures scheduled with no competent named staff member allocated.
H08

Home therapy supplier and service continuity failure

Supplier Before 9 After 4

Home oxygen, positive airway pressure supplies or consumables stop arriving because a supplier fails, a delivery is missed or a contact is unavailable, leaving patients without therapy.

Who or what is affected: Home therapy patients, carers and the service

Causes

Reliance on a single supplier, transport disruption and unclear handover of patient contacts.

Consequences

Therapy interruption, hospital admission and carer distress.

Existing controls

  • Supplier contracts include a stated response time.
  • Patients are given a service contact number.

Control gaps

Not all patients know who to call out of hours when a delivery is late.

Additional controls

  • Respond: Maintain an agreed escalation route to a second supplier for urgent supply.
  • Recover: Review contingency supplies and patient instructions with each patient every six months.
Likelihood 3 x impact 3 before; 2 x 2 after Owner: Supplier and contracts manager Target: Within 60 days Early warning: Patient therapy deliveries missed or delayed beyond the agreed window.

Rating method and evaluation

Each risk is rated on two five-point scales. Likelihood runs from Rare to Almost certain, and impact runs from Minimal to Severe, including harm to patients. Multiplying the two gives a score from 1 to 25, placed in one of four bands: Low from 1 to 4, Medium from 5 to 9, High from 10 to 16 and Critical from 17 to 25. Inherent risk is scored before any controls. Residual risk is scored after existing and additional controls, and it must never be higher than the inherent score. Patient harm is weighted heavily, so a risk that could cause serious harm is not rated down only because it has not yet happened. Critical risks need immediate senior attention and a dated plan, High risks need a named owner and a plan within the stated timeframe, Medium risks need routine controls and checks, and Low risks are accepted and watched. Frontline staff, patients where appropriate, and a second reviewer challenge the ratings. Any indicator reaching its threshold triggers a rating review, and specialist clinical review is required before any clinical change.

Likelihood, impact and rating bands

Likelihood

  • 5 Almost certain: Expected to happen in most circumstances.
  • 4 Likely: Will probably happen in many circumstances.
  • 3 Possible: Could happen at some time.
  • 2 Unlikely: Not expected, but it could happen.
  • 1 Rare: Only in exceptional circumstances.

Impact

  • 1 Insignificant: No lasting effect. Handled within routine work.
  • 2 Minor: Small effect that is quickly corrected.
  • 3 Moderate: Noticeable effect that needs managed effort to correct.
  • 4 Major: Serious effect on people, delivery or reputation.
  • 5 Catastrophic: Severe or lasting effect that threatens the whole activity.

Bands (likelihood x impact)

  • Low (1 to 4): Accept and monitor.
  • Medium (5 to 9): Manage with routine controls.
  • High (10 to 16): Senior attention and a treatment plan.
  • Critical (17 to 25): Act first. Do not proceed until reduced.

Monitoring, escalation and review

Review this assessment every 6 months, and sooner when an indicator below reaches its threshold.

Early-warning indicators and escalation thresholds
Indicator to watchEscalate when
Patients on respiratory wards with an early warning score above the agreed threshold and no documented review within the set time.Escalate to the duty clinical lead at once, and to the clinical director if the review is still missing after one hour.
Ventilator or oxygen alarms overridden or silenced without a documented reason.Escalate to the biomedical engineering lead at once, and remove the device from use until it is checked.
Fit test or hand hygiene audit records overdue for any respiratory area.Escalate to the infection prevention lead when overdue by 14 days, and to the service board after 30 days.
Patient record access by staff outside their care team or the sleep service.Escalate to the information governance lead within one working day for review.
Procedures recorded without a signed consent form or a documented decision on the day.Escalate each case to the clinical governance lead, and review the team's practice within 30 days.

Contingency arrangements

If a serious event occurs, such as an outbreak on a ward, a ventilator failure, a sentinel deterioration or a confirmed privacy breach, the duty clinical lead takes charge and makes the patient safe first. Equipment is removed from use and backup devices are brought in. Infection control, the information governance lead and the medical director are informed at once. Patients and families are told what happened early and plainly, and records are preserved. Oxygen and therapy supply is protected through a named supplier escalation route.

Prioritized action plan

  1. Introduce a structured handover and early warning escalation tool, owner clinical lead for respiratory care, within 30 days.
  2. Complete fit testing and isolation room checks for all respiratory areas, owner infection prevention lead, within 30 days.
  3. Test ventilator and oxygen alarms against a written checklist, owner biomedical engineering lead, within 45 days.
  4. Audit consent and procedure records against the local policy, owner clinical governance lead, within 60 days.
  5. Confirm the home oxygen supplier escalation route and a backup supplier, owner supplier and contracts manager, within 60 days.

Conclusion

Safe respiratory and sleep care rests on steady habits: structured handovers, timely escalation, tested equipment, careful consent, tight privacy and clear records. The highest scores sit with deterioration and infection, and each has actions that bring the residual score down. Treat the register as a living record, review it on the stated cycle, and seek qualified clinical, legal and medical device advice for any real decision.
